My thoughts on «IT i Praksis»

How can the public sector move faster

On August 10th IKT-Norge, Visma and Rambøll presented their 10th Annual report called “IT i Praksis”. It’s a survey meant to look at the maturity of practical IT use mainly in the public sector of Norway. It’s a huge report and I won’t cover all the topics here but there were a couple of things that stood out. The survey really boils down to the word digitalization. How can the public sector move faster so their users get the best digital experience possible?

This isn’t just a challenge for the public sector. It’s the same challenges if you are a retailer, a bank or really any other business where you need to connect with users in a digital way. There is one significant difference though, the ability to organize and the funding.

My take on Data Lake

The place for holding the truth

(I’m a poet and I know it)

I have been spending a lot of time warning people about the pitfalls, or rather deep ends, of the Data Lakes and Big Data initiatives. First, I want to state that I think the Data Lake as a concept is a great idea, but it needs to co-exist with your more traditional data architecture.
So, what I’m discussing in this post is my take on the total data architecture as I see it in today’s data age.


We all know the data warehouse mantra “One single version of the truth” or the variance “One single source of the truth”. The single source statement will be even less relevant with the coming of Big Data. But the one single version of the truth is probably even more important now in the big data age. You need one place to implement your business rules, and place to contain the truth. What we see now is that the place for holding the truth is not always in the same place.

Self-Service Data Preparation, why would you do that?

A tool is only a tool

In my previous posts, I have talked a lot about preparing your data and not forgetting your structured data in this time of Big Data, IOT and other cool stuff. Today I thought I’d take a step back and try to explain what our company do when it comes to preparing and structuring data and discuss how this can be a viable option for you.

So, what is Xpert BI?

We call it Self-Service data preparation or data warehouse automation. So, what does that mean and why should you do this instead of doing traditional ETL or ELT?

9 days and 8 nights in London

The data warehouse is still sexy

I just got back from a long and exiting trip to London, where BI Builders has been sponsoring two big events. First Big Data World, where I was a speaker and then the Gartner Analytics Summit, where my colleague Anja was a speaker. And I would like to share my thoughts and key takeaways from this inspiring trip.

So firstly, Big Data World, a huge conference that was co-located with four other conferences; Smart IOT, Cloud Security Expo, Cloud Expo and Data Centre World.

As you probably can imagine the buzz words flew high here, Big Data vendors in all shapes and sizes had a booth and it was amazing to both hear about and get demonstrations of how cloud based, non-structured data could be utilized. There are a lot of upcoming smart software and technics that will help us utilise our data in new and exciting ways.

Are we heading towards chaos? Or am I just getting old?

Write 500 lines of 500, pray and press F8

Last night I was attending an after work meet up where the topic was “Clash Of The Titans”. Microsoft, IBM, SAP and Oracle was presenting their BI and analytic solutions, both what they can offer today and how their future releases will be.

Remembering back to the year 2000 when I started my first job as a data warehouse developer, we programmed SAS code without any intellisense on a dark blue background with a white font.

After writing 500 lines of code we said a small prayer and then we pressed F8. Usually we got lucky, other times we didn’t, and had to use the rest of the day finding that small typo or looking for that breach in logic that didn’t give us the result we wanted.

Why are we only talking about lakes, reservoirs, swamps and clouds?

Hadoop Cluster Quote

The buzzwords and the endless possibilities that can be made in the cloud seems to be on everybody’s minds these days. Did we forget our core business?

At the breakfast table at the TDWI conference in February 2016 I met two gentlemen and we started talking about Big Data, cloud BI and the other buzzwords. They told me a story from their company.

“One day my boss comes into my office and asked, how are we on big data? I had to ask him back, what do you mean? My boss asked again, how are we on big data? Do we have Hadoop? And I said No? Well, we need that, my boss replied and walked out the door. So now we have a Hadoop cluster in the cloud with little or no data and we really don’t know why we need it, but I’m sure my boss got his bonus!”
